Disable "free the fish"

Hi guys,

I've spent a good while googling this, and haven't found it yet. Basically, rather than knowing how to stop it once it's started, could anyone please tell me how to disable "free the fish" so it doesn't work in the first place? Because it's not a command, I don't know what I can do. I've tried using

Code:

---

alias free=""

---

in the hope that it would be intercepted, but no.

Cheers!

Might check this Ubuntu forum link:

You should also be able to edit the panel to remove it, the fish icon at the bottom.
